Pulsate [iPhone, Sound]

Created by the team behind Audio Tool, Pulsate is a sound toy, an instrument which uses pulse as a way to create sound. Tapping on the screen creates circles which grows in scale. When two or more circles touch, they produce a sound. You can create as many circles as you like, adjust the sound wave, delay, BMP and more from the settings panel.

Simple, minimal and very enjoyable.
